Challenge Problems
Push your limits with advanced challenges
A pendulum of mass 2 kg swings with an angular acceleration of 1.5 rad/s². Calculate the resulting tangential force acting on the pendulum bob.
💡 Hint: Use the length of the pendulum as the radius.
A slider-crank mechanism has a crank radius of 0.75 m and an angular velocity of 4 rad/s. Determine the centripetal force for a mass of 3 kg moving in a circle.
💡 Hint: Make sure to square the angular velocity before multiplying.
